Which are the online trophies?

Was going to wait until I at least beat infamous one, but I just learned today that this game has online trophies. What are those trophies? I want to know so I can grind them out, if they're accessible from the beginning.

They are simply user generated missions, and you can access them during the main story, although not right from the beginning I think.

You can just search "easy missions" or "1 sec missions" or stuff like that, it's a very easy trophy.

What he said.

It's really no big deal at all, just a way for players to try out the UGC missions. Just like the rest of the game, it's still single-player, so don't worry about playing with other people if things like that concern you.
